Molecular Mechanisms of Phosphate Use Efficiency in via TLL1.

Beneficial fungi are promising tools for enhancing plant growth and crop yield in stressful environments. TLL1 (POT1) was identified as a potential biofertilizer enhancing plant growth and phosphate use efficiency especially under phosphate deficiency stress. Hence, we attempted to explore bioinformatic insights into how POT1 enhances plant growth under phosphate starvation.

Mitigating aluminum toxicity and promoting plant resilience in acidic soil with TLL1.

Aluminum (Al), prevalent in the crust of the Earth, jeopardizes plant health in acidic soils, hindering root growth and overall development. In this study, we first analysed the Al- and pH- tolerance of the TLL1 strain (POT1; NRRL:68252) and investigated the potential for enhancing plant resilience under Al-rich acidic soil conditions. Our research illustrates the extraordinary tolerance of POT1 to both high Al concentrations and acidic conditions, showcasing its potential to alleviate Al-induced stress in plants.

Plant growth promotion under phosphate deficiency and improved phosphate acquisition by new fungal strain, TLL1.

Microbiomes in soil ecosystems play a significant role in solubilizing insoluble inorganic and organic phosphate sources with low availability and mobility in the soil. They transfer the phosphate ion to plants, thereby promoting plant growth. In this study, we isolated an unidentified fungal strain, POT1 ( TLL1) from indoor dust samples, and confirmed its ability to promote root growth, especially under phosphate deficiency, as well as solubilizing activity for insoluble phosphates such as AlPO, FePO·4HO, Ca(PO), and hydroxyapatite.

Genetic analysis of plant endophytic Pseudomonas putida BP25 and chemo-profiling of its antimicrobial volatile organic compounds.

Black pepper associated bacterium BP25 was isolated from root endosphere of apparently healthy cultivar Panniyur-5 that protected black pepper against Phytophthora capsici and Radopholus similis - the major production constraints. The bacterium was characterized and mechanisms of its antagonistic action against major pathogens are elucidated. The polyphasic phenotypic analysis revealed its identity as Pseudomonas putida.
